Anthony Bourdain and Vegetarians/Vegans

I must admit, I'm basically a vegetarian. From time to time I'll eat a crab or a some oysters (because they are "sustainable") but that happens about once or twice a year. My reasons for being a veg are not that I don't love food of all kinds, but that I just can't bring myself to partake in food that I believe is seriously harming the planet. But, I say, live and let live. I don't need to look down on others. But, as much as I love Anthony's show, his aggressive "anti-veg" stance is, in my opinion, just ignorant. What do y'all think? Do you agree with him and if so, why? I need help understanding his viewpoint. Maybe I'll stop being irritated at him if someone can explain.
